I have two Zigbee remote keypads, one I keep downstairs, one upstairs. I recently added a new feature that triggers when "button 2" of either keypad is pressed. Over the last week I started getting spurious triggers from keypad #2, button 5. They are random and according to the logs are only coming from keypad #2 button 5. Keypad #1 is "quiet" as are all the other buttons on keypad #2.
I studied the logs and don't see anything unusual. I can push the button on the keypad and it responds correctly every time. As a sanity check I removed the battery from keypad #2, and a short time later I got another spurious trigger, from keypad #2 according to the logs.
At this point I assume there is an interfering signal that's being interpreted as keypad #2, button 5. I've been running my hub for many years and never had any issue like this. I thought Zigbee protocol would be pretty immune to such kinds of things (unlike X-10 that would give false triggers every day). Does anyone have experience with this? I think my only option is to abandon the use of "button 5" on that keypad.
Thanks.
It turns out my troubleshooting process was flawed. I had mixed up the two keypads in my head, mistakenly removing the battery from
